Applications of Overset Grid Technique to CFD Simulation of High Mach Number Multi-body Interaction/Separation Flow

Performance enhancement strategies for multi-block overset grid CFD applications

The overset grid methodology has significantly reduced time-to-solution of highfidelity computational fluid dynamics (CFD) simulations about complex aerospace configurations. The solution process resolves the geometrical complexity of the problem domain by using separately generated but overlapping structured discretization grids that periodically exchange information through interpolation. How...

Load Balancing Strategies for Multi-Block Overset Grid Applications

The multi-block overset grid method is a powerful technique for high-fidelity computational fluid dynamics (CFD) simulations about complex aerospace configurations. The solution process uses a grid system that discretizes the problem domain by using separately generated but overlapping structured grids that periodically update and exchange boundary information through interpolation. For efficie...

Dynamic Overset Grid Computations for CFD Applications on Graphics Processing Units

The objective of the present work is to discuss the development of a 3D Unstructured-Overset grid Computational Fluid Dynamics (CFD) solver on General Purpose Graphics Processing Units (GPGPUs). As an extension of our previous work on 2D/3D overset grid computations for compressible/incompressible ows on static grids[1][2], the current paper focuses on moving overset grids with dynamic domain c...
